DC24EE

DC24EE

Superheat panel-mounting controller with management of PWM electronic expansion valve

IP65 enclosure, display, power supply, 230 VAC, 3 relays, 1 electronic expansion valve output (triac) 24-240 VAC, 5 PT 1000 inputs, 1 0-10 V input, 2 digital inputs, bus interface, clock, plug-in terminals.
Compatible with all major pulse width modulated electronic expansion valves on the market (e.g. Danfoss AKV).

The DC24EE controller has very compact dimensions, which makes it easy to install directly in the cabinet.

The DC24EE module is a universal controller that performs measurement, monitoring and control functions for the following applications:

– control of cooling cabinets or cold rooms (MT and LT refrigeration) with superheat control using electronic expansion valves,
– compressor control,
– condenser management,
– humidity control,
– management of air conditioning and lighting zones,
– input-output mode.

The module can be mounted in the front of a cabinet or integrated in a display case.
The DC24EE module can be programmed using the Teleswin supervision software or directly via the buttons on the front panel. The integrated display shows the values measured by the connected sensors and is used for programming the parameters.
